If you are referring to photoshop 2, then it's really time to upgrade :-) I think I stopped using photoshop 2 around 1993(?) and upgraded to photoshop 3 (I think it allowed masks for the first time). If you are using Photoshop CS2, and happy with LR2.3 for all your needs, so be it... I can recommend upgrading to CS4, it has tons of nice features, plus bridge does a couple of things that LR does, especially in RAW.
